[SR-Users] driver error: Can't connect to MySQL server with kamailio 5.3.x and mysql-config-groups

Hi Sergey,


That string I forgot to remove. I add the company name to self build RPMS
to see what's from kamailio and what's build by myself. You can ignore
that.

The strange python23 dependency comes as result of building the RPMS with
the shipped spec file. I only changed the version and build string (as
described above).

And with branch 5.2 I don't have that behaviors.

Anyway. I try to use the Kamailio builded versions if it's possible, in
this testing case I used the build process by myself.

Cheers
Karsten
